. ADJUSTABLE TIRE-LEVER.

To all whom it may confirm: V v 1 Be it known that I, ',W1Lr,1nM orrN OENS, subject ofthe King ofGreat Britain and Ireland, residing at, 6StiPauls street, Chippenham inthe county of Wiltsh1re, England, haveinvented certain new and useful Improvements in Adjustable T re. Levers,of whichthe followingis a spee1fi-- cation. I

This invention relates to improvements in tire levers and refers moreparticularly .to the arrangement and method of applying or manipulatingtire levers of the type described in my co-pendin apphcation for LettersPatent of the, 1 Inited States of America Serial No. 323959, datedSeptember 15th, 1919.

In the pr'or application I have described and illustrated a tire leverhaving a cranked end, one part of ,WlllGh 1s arranged to engage one sideof the wheel T1111, while another part is adapted to engage the edge ofthe tire on the opposite side of the wheel rim, so that on the leverbeing moved about its end connected to the rim of the wheel, the edge ofthe tire on the opposite side is forced over the rim.

The object of the present invention consists in an improved arrangementandconstruction whereby the lever may be adjusted for use with any sizeof wheel rim or tire, for motor car, motor-cycle or bicycle wheels, andalso to further facilitate the operation of removing the tire from saidwheel rims.

In order that the invention may be readily understood, I will nowproceed to describe the same with reference to the accompanying sheet ofillustrated drawings, in which:

Figure 1 is a side view showing the device being used for attaching atire to the wheel rim, the latter being shown in section.

Fig. 2 shows the device being used to remove the tire from the wheelrlm.

Fig. 3 is a plan view of the manipulating lever.

Figs. 4 and 5, are side View and front elevation of the supporting linkfor one end of the manipulating lever.

Figs. 6 and 7 show in side and front elevation respectively the pivot orpin by which the manipulating lever is connected to the supporting link,and

h e-lever when the latter being used to remove the tire. g I

The manipulating lever d isformed inter mediate its ends with a shoulderorprojection' a and at one end with a curved or'tonguelike member a forapurpose hereinafter described. Theoppositeend of the lever is bent orotherwise formed with a downwardly? extending portion a and a forwardlyprojecting portion a The portion a is pref-. erably screwed externallywhile the portions a? and a? may be substantially flat, and preferablyprovided with a strengthening rib a on the inner side as shown in Fig.;1.

' Thescrewed forwardly projectingend of the lever is supported byasubstantially 8-,

shaped link or the like 1), the, upper end 19 of which is shaped toembrace or suitably engage the edge o of the wheel rim 0, while itslower end carriesa cylindricalpin or spindle d. The lower end of thesupporting link is formed with a slot 6 extending longitudinally upwardfrom its end as shown in Fig. 5. The pin d or the like, is of such asize as to snugly and rotatably fit into the bifurcated ends 6? of thelink 6 and is provided with a screwed hole into which the is screwed,the slot Z2? permitting rotation ting or attaching the tire e to the rim0, the upper end of the link I) is engaged over the edge 0 of the wheelrim 0 on the opposite side to that over which the edge of the tire is tobe fitted. The manipulating lever is now rotated about the axis of theforwardly projecting screwed portion 0, until thecorrect adjustment isobtained to cause the shoulder a to engage the edge of the tire. Thelever is now raised, being moved about the axis of the pin 03 and theedge of the tire may be easily forced over the edge 0 of the wheel rim 0as will be readily under stood.

In order to facilitate the. operation of re- 'moving the tire from thewheel rim, I proscrewed end of the portion a of the lever gage the edge0 of the wheel rim 0, while its opposite end is provided with atransverse slot F. The plate may be made of any suitable length and ispreferably curved being forced down the outer end of the leveras shownso as to extend to a point in the path of the lever a when the latter is-manipulated as shown in Fig. 2. In thisfigure the upper curved ortongue-like portion (1 is engaged beneath the edge of the: tire. andforced down to cause the edge of the.

tire to bedisengaged from the wheel rim.

When this operation is being effected, it has been found very diiiicultto'retain the re: moved portion of the tire while other por-,

tions thereof around-the circumference of the wheel are similarlytreated. To enable the tire to be easily removed, the retaini'n'g hookis attached to the edge of the rim opposite to that from which the tireis to be removed, and on the lever a, which has been engaged beneath theedge of the tire,

covers of pneumatic "tires, comprising. a manipulating lever, aprojection on said lever intermediate its ends adapted to engage oneedge of the tire, an externallythreaded forwardly projecting portion onsaid lever, a link of substantially S-shape adapted to embracetheopposite'edge of the wheel rim,- a cylindrical member rotatablymounted in the low'er'e 'nd of said' link and'formed with a screwed holeto receive the externally screwed forwardly projecting portion of thelever, for the purposes described.
